The #44 Kadee® Magne-Matic® Coupler
features a Metal Coupler, #634 Centering
Spring, insulated #232 Draft Gear Box and
Lid with side and center screw holes for
mounting, which is the same gear box
which comes in the NO.5®coupler package.

The #44 Coupler may be mounted with
the supplied #232 draft gear box, with the
manufacturers cast-on coupler pockets, the
insulated #213 draft gear box, which is the
same gear box that the 20 Series couplers
use, (Purchased Separately) or the insulated
#233 draft gear box which is the same gear
box that the 30 Series couplers use.
(Purchased Separately).

The 40 Series Couplers are metal
equivalents to the 20 and 30 series couplers
and have the same dimensions as their
corresponding coupler numbers, such
as the #44 is the same as the #24 and
#34 Couplers. These were developed to
provide the modeler a metal offset series
of couplers to complement the NO.5®Coupler.

Although the 20 and 30 Series Couplers
are made of very strong plastic many modelers
like to use only metal couplers which of course
are stronger. The strength of metal couplers
over plastic sometimes is only a matter of
personal choice and not the particular
application, however there are certainly
many reasons to use metal couplers when
the extra strength and rigidity is needed.

It is not recommended to use a metal
coupler directly on a metal surface or in a
metal draft gear box to avoid the possible
electrical crossover or shorting that may
cause damage. Use the provided insulated
draft gear box or the appropriate insulated
plastic 20 or 30 Series Couplers.
